9 SAFETY vacon 7 1. SAFETY ONLY A COMPETENT ELECTRICIAN MAY CARRY OUT THE ELECTRICAL INSTALLATION 1.1 Warnings WARNING The components of the power unit of the inverter are live when the Vacon NX is connected to DC supply. Coming into contact with this voltage is extremely dangerous and may cause death or severe injury. The control unit is isolated from mains potential. The supply and motor terminals are live when the Vacon NX is connected to DC supply, even if the motor is not running. The control I/O-terminals are isolated from the mains potential. However, the relay outputs and other I/O-terminals may have dangerous control voltage present even when the Vacon NX is disconnected from the DC supply.. The inverter has a large capacitive leakage current. If the inverter is used as a part of a machine, the machine manufacturer is responsible for providing the machine with a main switch (EN ). Only spare parts delivered by Vacon can be used. 1.2 Safety instructions The Vacon NX inverter is meant for fixed installations only. Do not perform any measurements when the inverter is connected to the DC supply. After having disconnected the inverter from the DC supply, wait until the fan stops and the indicators on the keypad go out (if no keypad is attached see the indicator through the keypad base). Wait 5 more minutes before doing any work on Vacon NX connections. Do not even open the cover before this time has expired. Do not perform any voltage withstand tests on any part of Vacon NX. There is a certain procedure according to which the tests shall be performed. Ignoring this procedure may result in damaged product. Prior to measurements on the motor or the motor cable, disconnect the motor cable from the inverter. Do not touch the components on the circuit boards. Static voltage discharge may damage the components. Before connecting the inverter to DC supply, make sure that the Vacon NX front and cable covers are closed. Päivystys: vacon@vacon.com 1

10 8 vacon SAFETY 1.3 Earthing and earth fault protection The Vacon NX inverter must always be earthed with an earthing conductor connected to the earthing terminal. The earth fault protection inside the inverter only protects the inverter against earth faults in the motor or the motor cable. Due to the high capacitive currents present in the inverter, fault current protective switches may not function properly. If fault current protective switches are used, they need to be tested with earth fault currents present during possible fault situations. 1.4 Running the motor Warning symbols For your own safety, please pay special attention to the instructions marked with the following symbols: = Dangerous voltage WARNING HOT SURFACE = General warning = Hot surface Risk of burn MOTOR RUN CHECK LIST WARNING Before starting the motor, check that the motor is mounted properly and ensure that the machine connected to the motor allows the motor to be started. Set the maximum motor speed (frequency) according to the motor and the machine connected to it. Before reversing the motor, make sure that this can be done safely. Make sure that no power correction capacitors are connected to the motor cable. Make sure that the motor terminals are not connected to mains potential. 1 Puhelin: Fax:

11 Turvallisuus vacon 9 2. EU DIRECTIVE 2.1 CE marking The CE marking on the product guarantees the free movement of the product within the EEA (European Economic Area). It also guarantees that the product complies with applicable directives (for example, the EMC directive and other possible so-called new method directives). Vacon NX inverters carry the CE label as a proof of compliance with the Low Voltage Directive (LVD) and the Electro Magnetic Compatibility (EMC) directive. SGS FIMKO has acted as the Competent Body. 2.2 EMC directive Introduction The EMC Directive provides that the electrical apparatus must not excessively disturb the environment it is used in, and, on the other hand, it shall have an adequate level of immunity toward other disturbances from the same environment. The compliance of Vacon NX inverters with the EMC directive is verified with Technical Construction Files (TCF) and checked and approved by SGS FIMKO, which is a Competent Body. The Technical Construction Files are used to authenticate the conformity of Vacon inverters with the Directive because it is impossible to test such a large product family in a laboratory environment and because the combinations of installation vary greatly Technical criteria Our basic idea was to develop a range of inverters offering the best possible usability and costefficiency. EMC compliance was a major consideration from the outset of the design. Vacon NX inverters are marketed throughout the world, a fact which makes the EMC requirements of customers different. As far as immunity is concerned, all Vacon NX inverters are designed to fulfil even the strictest requirements Vacon inverter EMC classification Factory delivered Vacon NX inverters are Class T equipment, which fulfil all EMC immunity requirements (standards EN , and EN ). Class T: Class T equipment have a small earth leakage current and can be used with floating DC input. If they are used with other supplies, no EMC requirements are complied with. Warning: This product is of the restricted sales distribution class according to IEC In residential areas, this product may cause radio interference in which case the user may be required to take adequate measures.

15 technical data vacon TECHNICAL DATA 4.1 Introduction The figure below presents the block diagram of the Vacon NX inverter. The inverter mechanically consists of two units, the Power Unit and the Control Unit. The Power Unit contains an inverter bridge which consists of IGBT switches and produces a symmetrical, 3-phase PWM-modulated AC voltage to the motor. To protect the DC-link capacitors, the Power Unit also contains a charging circuit for controlled DC-link charge. Use the B+ and DCterminals in order to bypass the charging circuit. The Motor and Application Control Block is based on microprocessor software. The microprocessor controls the motor based on the information it receives through measurements, parameter settings, control I/O and control keypad. The motor and application control block controls the motor control ASIC which, in turn, calculates the IGBT positions. Gate drivers amplify these signals for driving the IGBT inverter bridge.

16 14 vacon technical data The control keypad constitutes a link between the user and the inverter. The control keypad is used for parameter setting, reading status data and giving control commands. It is detachable and can be operated externally and is connected via a cable to the inverter. Instead of the control keypad, a PC can be used to control the inverter if connected through a similar cable (VACON RS232PC 1.5M). The basic control interface and the parameters (the Basic Application) are easy to use. If a more versatile interface or parameters are required, a more suitable application can be chosen from the "All in One+" Application Package. See the "All in One+" Application Manual for more information on the different applications. Optional I/O expander boards that increase the number of inputs and outputs to be used are also available.

A cable entry gland should be used at the motor cable end to reach the EMC levels, see Table 6-1. Use cables with a heat resistance of at least +60C. The cables and the fuses must be sized according to the inverter nominal output current which you can find on the rating plate. Installation of cables according to UL regulations is presented in Chapter and ar fuse sizes in Tables 6-2 and 6-3. The minimum dimensions of the Cu-cables are shown in Table 6-4. If the motor temperature protection of the drive (see Vacon All in One Application Manual) is used as an overload protection, the cable shall be chosen accordingly. If three or more cables are used in parallel for bigger units, each cable requires a separate overload protection. These instructions apply only to installations with one motor and one cable connection from the inverter to the motor. In any other case, ask the factory for more information.

34 32 vacon cabling and connections Installation instructions Before starting the installation, check that none of the components of the inverter are live. If the inverter is installed outside the cubicle, cabinet or device space, you need to install a separate inverter cover (see, for example Figure 6-3 ) in accordance with protection class IP21 requirements. There is no need to install the inverter cover if the inverter is installed in a cubicle, separate cabinet or device space. Place the motor cables sufficiently far from other cables: Avoid placing the motor cables in long parallel lines with other cables If the motor cables runs in parallel with other cables, note the minimum distances between the motor cables and other cables given in the table below. The given distances also apply between the motor cables and signal cables of other systems. The maximum length of the motor cables is 300 m (units with power greater than 1.5 kw) and 100 m (units with power from 0.75 to 1.5 kw). The motor cables should cross other cables at an angle of 90 degrees. 4 If cable insulation checks are needed, see Chapter. 6 Tel: Fax:

Basic and option board connections on the control board When the inverter is delivered from the factory, the control unit usually includes two basic boards (I/O board and relay board), which are normally installed in slots A and B. On the next pages you will find the arrangement of the control I/O and the relay terminals of the two basic boards, the general wiring diagram and the control signal descriptions. The I/O boards mounted at the factory are indicated in the type code. For more information on the option boards, see Vacon NX option board manual (ud741). The control board can be powered externally (+24V) by connecting the external power source to bidirectional terminal #6 (see Table 6-9). This voltage is sufficient for parameter setting and for keeping the fieldbus active. Note! If the +24V input of several inverters are connected in parallel, we recommend to use a diode in terminal #6 to avoid the current to flow in opposite direction, which might damage the control board.

Parameter values can be edited by entering the Parameter Menu from the Main Menu when the location indication M2 is visible on the first line of the display. The value editing procedure is presented in Figure 7-1. Pressing Menu button right once takes you to the Parameter Group Menu (G#). Locate the desired parameter group by using the Browser buttons and press Menu button right again to see the group and its parameters. Use the Browser buttons to find the parameter (P#) you want to edit. Pressing Menu button right takes you to the edit mode. As a sign of this, the parameter value starts to blink. You can now change the value in two different ways: Set the desired value with the Browser buttons and confirm the change with the enter button. Consequently, the blinking stops and the new value is visible in the value field. Press Menu button right once more. Now you will be able to edit the value digit by digit. This may come in handy, when a relatively greater or smaller value than that on the display is desired. Confirm the change with the enter button. The value will not change unless the Enter button is pressed. Pressing Menu button left takes you back to the previous menu. Several parameters are locked, i.e. cannot be edited, when the drive is in RUN status. If you try to change the value of such a parameter the text *Locked* will appear on the display. The inverter must be stopped to edit these parameters. The parameter values can also be locked using the function in menu M6 (see Chapter6.5.2)). You can return to the Main menu any time by pressing Menu button left for 1 to 2 seconds. The basic application package "All in One+" includes seven applications with different sets of parameters. You will find the parameter lists in the Application Section of this manual. Once in the last parameter of a parameter group, you can move directly to the first parameter of that group by pressing Browser button up. See the diagram for parameter value change procedure on page 53.

When a fault brings the inverter to a stop, the location indication F1, the fault code, a short description of the fault, and the fault type symbol (see Chapter ) will appear on the display. In addition, the indication FAULT or ALARM (see Figure 7-1 or Chapter 7.1.1) is displayed and, in case of a FAULT, the red LED on the keypad starts to blink. If several faults occur simultaneously, the list of active faults can be browsed with the Browser buttons. The memory of active faults can store a maximum of 10 faults in the order of appearance. The display can be cleared with the reset button and the read-out will return to the same state it was in before the fault trip. The fault remains active until it is cleared with the reset button or with a reset signal from the I/O terminal. Note! Remove external Start signal before resetting the fault to prevent unintentional restart of the drive. Normal state, no faults Active faults F Fault types The NX inverter has four types of faults.

59 control keypad vacon 57 Fault type symbol A (Alarm) F (Fault) AR (Fault Autoreset) FT (Fault Trip) Table 7-1. Fault types Meaning This type of fault is a sign of an unusual operating condition. It does not cause the drive to stop, nor does it require any special actions. The 'A fault' remains in the display for about 30 seconds. An 'F fault' makes the drive stop. Actions need to be taken to restart the drive. If an 'AR fault' occurs the drive will stop immediately. The fault is reset automatically and the drive tries to restart the motor. Finally, if the restart is not successful, a fault trip (FT, see below) occurs. If the drive is unable to restart the motor after an AR fault an FT fault occurs. The 'FT fault' has basically the same effect as the F fault: the drive is stopped. 24-hour support: +358-(0) vacon@vacon.com 7

84 82 vacon commissioning 8. COMMISSIONING 8.1 Safety Before commissioning, note the following directions and warnings: WARNING HOT SURFACE Internal components and circuit boards of the inverter (except for the galvanically isolated I/O terminals) are live when Vacon NX is connected to mains potential. Coming into contact with this voltage is extremely dangerous and may cause death or severe injury. The motor terminals U, V, W and the DC-link/brake resistor terminals+/- are live when Vacon NX inverter is connected to DC supply, even if the motor is not running. The control I/O-terminals are isolated from the mains potential. However, the relay outputs and other I/O-terminals may have a dangerous control voltage present even when Vacon NX is disconnected from DC supply. Do not make any connections when the inverter is connected to the DC supply. After having disconnected the inverter, wait until the fan stops and the indicators on the keypad go out (if no keypad is attached see the indicator through the keypad base). Wait 5 more minutes before doing any work on Vacon NX connections. Do not open the cover before the time has expired. Before connecting the inverter to DC supply make sure that the Vacon NX front cover is closed. When running, the side of inverter FR8 is burning hot. Do not touch it with bare hands! When running, the back of inverter FR6 is burning hot. Therefore it MUST NOT be mounted onto a surface which is not fireproof. 8.2 Commissioning the inverter 1 Read carefully the safety instructions in Chapter 1 and above and follow them. 2 After the installation, make sure that: both the inverter and the motor are grounded the DC supply and motor cables comply with the requirements given in Chapter the control cables are located as far as possible from the power cables (see Chapter 6.1.2, step 2) and the shields of the shielded cables are connected to protective earth wires may not touch the electrical components of the inverter. the common inputs of digital input groups are connected to +24V or ground of the I/O terminal or the external supply. 3 Check the quality and quantity of cooling air (See Chapter 5.2 and Table 5-6)..

At least the following parameters should be set: motor nominal voltage motor nominal frequency motor nominal speed motor nominal current You will find the values needed for the parameters on the motor rating plate. 8 Perform run test without motor Perform either Test A or Test B: A Controls from the I/O terminals: Turn the Start/Stop switch to ON position. Change the frequency reference (potentiometer) Check in the Monitoring menu M1 that the value of Output frequency changes according to the change of frequency reference. Turn the Start/Stop switch to OFF position. B Control from the control keypad: Change the control from the I/O terminals to the keypad as advised in Chapter Press the START button on the keypad START. Move over to the Keypad control menu M3 and Keypad Reference submenu (see Chapter ) and change the frequency reference with the Browser buttons + -.

86 84 vacon commissioning 9 Run the start-up tests without the motor being connected to the process. If this is not possible, make sure that running each test is safe prior to running it. Inform your coworkers of the tests. Switch off the DC supply voltage and wait until the drive has stopped as advised in Chapter 8.1, step 5. Connect the motor cable to the motor and to the motor cable terminals of the inverter. Make sure that all Start/Stop switches are in Stop positions. Switch the supply voltage ON Repeat test 8A or 8B. 10 Connect the motor to the process (if the start-up test was run without the motor being connected) Before running the tests, make sure that this can be done safely. Inform your co-workers of the tests. Repeat test 8A or 8B. 8 Tel: Fax:

87 fault tracing vacon FAULT TRACING When a fault is detected by the inverter control electronics, the drive is stopped and the symbol F together with the ordinal number of the fault, the fault code and a short fault description appear on the display. The fault can be reset with the reset button on the control keypad or via the I/O terminal. The faults are stored in the Fault history menu M5, which can be browsed. The table below contains all the fault codes. The fault codes, their causes and correcting actions are presented in the table below. Shadowed faults are A faults only.
